Quick coupling and release mechanism for buckets

摘要

A quick coupling and release mechanism for attaching a material handling bucket to the free end of a scoop arm extending from a loader or backhoe. The quick coupler has three spaced apart ends including a first end connected to a push-pull link by a releasable pin, a second end pivotally mounted between bifurcated ends on the loader arm, and a third end which is slotted for selective engagement with a mounting pin on the bucket. The push-pull link may be connected at a first location to the quick coupler when it is desired to permit more angular displacement of the quick coupler or to a second location on the quick coupler when it is desired to permit less angular displacement of the quick coupler. Further, the quick coupler and bucket are pivotally connected to the loader arm by a single releasable pin for pivotal movement about a common pivot axis. A single operator can easily handle the entire coupling or uncoupling operation without special tools. Further, the quick coupler does not require a special bucket construction or the attachment of special parts to the bucket for its operability.
